Meteorological data outside
and inside the greenhouse were measured by two automatic
weather stations (Hobo, Onset Computer Corp., USA). The automatic
weather station inside the greenhouse was located in the
center of the greenhouse, and the outside one was 200 m away from
the greenhouse. The measured meteorological data included rainfall
(R), air speed at 2 m above ground (u2) and wind direction, solar
radiation (Rs), air temperature (Ta) and relative humidity (RH), but
the R, u2 and wind direction were not measured inside the greenhouse.
The data were measured every 5 s, and 15 min averages were
calculated and recorded using a data logger.
